SN74ALS257AD Overview
Providing this information in the 16-SOIC (0.154, 3.90mm Width) enables digital switch board space to be saved.As a result, it is packaged in the way of Tube.Mounting is performed using Surface Mount.the multiplexers uses an analog IC Multiplexer.A temperature of 0°C~70°C will not leave the turn signal swturn signal switchch susceptible to external influences.When operated with a 4.5V~5.5V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.Multiplexers from the 74ALS series can be used in a wide range of applications.This configuration includes 16 terminations as part of its basic functionality.The base part number is 74ALS257, which is also useful when looking up signal switch's related components.The multiplexer's system is powered by 5V voltage.Currently, this turn signal switch has a total of 16 component pins.A conductor terminates at GULL WING.This supply type employs Single.The board has 16 pins configured.The mounting point is Surface Mount.I would like to refer to the logic switch as a member of the ALS family.There are 2 bits signal multiplexer provides.It is advisable that the maximal supply voltage (Vsup) remains at 5.5V to avoid some unnecessary failures.During mux switch's normal operation, 5V is provided with a power supply.For the turn signal switch's operation, there are 1 outputs.Not being affected by the external factors, consumes 9mA current of multiplexer ic.The multiplexer provides 8 inputs.There are a total of 4 channels used for transmitting data in the turn signal switch's circuit.
